    Computer graphics and all the computer-aided drawing and manufacturing (CAD/CAM), scanning, and imaging technology is changing dentistry. Invisalign is a technology that straightens adult teeth using a series of clear, plastic, nearly invisible aligners. Though proprietary CAD/CAM software that does 3D modeling, the company creates the fixtures for orthodontists. For dental implants dentists make ... View full abstract»

    Pirates of the Caribbean-Battle for the Buccaneer Gold is an interactive theme park ride based on the classic Pirates of the Caribbean attraction at Disneyland. With themes and inspiration taken from the ride, this virtual interactive experience treats four guests to an overwhelming immersive adventure on the high seas. One guest steers at a real helm while the other three guests man six real cann... View full abstract»

    We address the problem of rendering large, unstructured volumetric grids and present a set of techniques that render arbitrarily large data sets on machines with limited memory. We present two techniques that vary in rendering speed, disk and memory usage, ease of implementation, and preprocessing costs. The first is a memory-insensitive rendering (MIR) technique that is completely disk-based and ... View full abstract»

  • Visualization of large data sets with the Active Data Repository

    We implement ray-casting-based volume rendering and isosurface rendering methods using the Active Data Repository (ADR) for visualizing out-of-core data sets. We have developed the ADR object-oriented framework to provide support for applications that employ range queries with user-defined mapping and aggregation operations on large-scale multidimensional data. ADR targets distributed-memory paral... View full abstract»

  • Massively parallel software rendering for visualizing large-scale data sets

    We describe two highly scalable, parallel software volume-rendering algorithms - one renders unstructured grid volume data and the other renders isosurfaces. We designed one algorithm for distributed-memory parallel architectures to render unstructured grid volume data. We designed the other for shared-memory parallel architectures to directly render isosurfaces. Through the discussion of these tw... View full abstract»

    Sandia National Laboratories use PC clusters and commodity graphics cards to achieve higher rendering performance on extreme data sets. The main obstacle in using cluster-based graphics systems is the difficulty in realizing the full aggregate performance of all the individual graphics accelerators, particularly for very large data sets that exceed the capacity and performance characteristics of a...

    Quantum computers will be useful for all kinds of computing. In addition to computer graphics they will have applications in cryptography, biology, and communications. We start with a look at the general principles of quantum mechanics as they apply to quantum computing. In the next issue, I present some of the mathematics behind actually creating quantum algorithms View full abstract»

    To employ direct volume rendering, TRex uses parallel graphics hardware, software-based compositing, and high-performance I/O to provide near-interactive display rates for time-varying, terabyte-sized data sets. We present a scalable, pipelined approach for rendering data sets too large for a single graphics card. To do so, we take advantage of multiple hardware rendering units and parallel softwa...

    We present an architectural approach based on parallel data streaming to enable visualizations on a parallel cluster. Our approach requires less memory than other visualizations while achieving high code reuse. We implemented our architecture within the Visualization Toolkit (VTK). It includes specific additions to support message passing interfaces (MPIs); memory limit-based streaming of both imp... View full abstract»

    Real-time underwater visualization has been extremely slow to develop within the offshore industry and has generally been limited to 2D representations of vessel positions on digital charts. Only recently have marine industries realized the potential of 3D real-time virtual environments and visualization systems for effective management planning and real-time situation awareness. We describe a rea... View full abstract»
